Crude oil is <u>refined to separate the chemicals used for gasoline, lubricants, plastics, and other products.</u>
<u />
- In a distillation tower, the crude oil is separated by boiling point after being heated by a furnace.
- The material is then transformed into finished goods like fuels like gasoline and diesel, as well as specialty items like asphalt and solvents, by using heat, pressure, or a catalyst.
- Ethane, liquid petroleum gas (LPG), and naphtha are the three main petrochemical feedstocks generated from crude oil.
- These are mostly employed in the creation of synthetic fibers, plastic polymers, and other petrochemical intermediates.
- With increased global income, demand for these products will only continue to rise.
